Bystanders who witnessed Saturday night's attack on Borough Market, near London Bridge, said they tried to stop the assailants from stabbing people by pelting them with glasses and bottles and hurling tables in their direction.
Multiple witnesses reported a vehicle veering off the road and hitting several pedestrians; others also said they saw a man with a knife.

In March, four people were killed in London after Khalid Masood rammed his auto into pedestrians on Westminster Bridge, before fatally stabbing a policeman outside the Houses of Parliament.
